First Vaccine - 7 months / male

Hello everyone, I has a stray cat few months ago. He was attack 2 time from pneumonia and survive. Now from last Sunday I start his vaccination. After his first Vaccine 2 days later he start sneezing. I am worried is this vaccine process or shell I take him to vet.

Second problem I am facing he have fleas also since last week. How to handle that? Because vet said don't shower him for one week after vaccine.

Don't know what to do? Worried!

The sneezing could be from the stress of the vet visit.  Watch him and if he gets more ill, take him back to the vet.  For the fleas, we give topical medication here.  Not sure if you have access to any medicine for fleas, but you can try putting a few drops of liquid soap into a glass of water.  Dip a comb in the water and then comb the kitty.

I will try tomorrow to find some medicine from pet shop. Then update.

Thank you.
